Lincoln LS Climate Control

Hey everyone, new to the forum... Can anyone help me out, I just recently purchased a 2004 LS V6 on saturday, I have a couple things that are going on thats bothering me...

1. The Heat doesn't work very well, it only comes on after im doing over 40+ mph, and not even that hot neither, even if I have the heat set to 90 degrees!

2. My Side view Mirror control button doesn't work properly, it can only set the mirrors downward but can't raise the mirrors upwards are turn them in or outward.

3. The Transmission feels like it engages hard sometimes coming back down from 5th to 4th or 4th to third im not quite sure, I drive with the shift selector on D5.

The car has 27K on it and it is a 2004, can I take it to a Lincoln Dealership and have this stuff checked out at no charge at all? Or will this stuff cost me a couple of $$$. I love this car and always wanted one, but little things like this turn me off about the car.

Considering it has a 48 month/50K mile warranty I'd say you're covered. It's a bumper to bumper warranty so you shouldn't be out anything other than time. Depending on your dealer they may also give you a free loaner while they check yours out.

The drivers side temperture control on my 00' LS for the heat/Air stays on heat even though the digital display changes on the dash. The passenger side control works fine and responds to temperture control changes. Any suggestions?B.

Akirby may be right, but there are also two different valving setups for the HVAC due to the Driver/Passenger controls. One of these could be malfunctioning.

But good luck getting it fixed. When mine had 60 degree air out the side vents and 110 degree air out the center stack, [non-permissible content removed] verified by Lincoln field engineering, Lincoln factory engineering's response was "Within Spec". They of course refused to show me the spec and refused to fix the car.

My 2000 LS blows hot air off and on when a big drop occurs with RPM's. Dealer flushed system once with some chemical and that worked for short time. Driver side gets extremly hot, passenger side barely cool.Dealer said a new valve would be needed at 700.00. Sure could use some help on this.Also just had new head gasket's installed, big buck's.

I'm assuming you want cold air on both sides? And it's not set on dual operation? IOW, one temp set point is displayed.

Sounds tricky to me. Cause there are two 'heater control valves' - one for driver and one for pass. So if driver's stuck on heat, why pass doesn't get cool? Could be some crossover heating effect? Anyway, my guess is that the dealer should replace the valve for the driver side. It's probably fairly simple to replace if you dare. Try not to get an air bubble in the system though.

I'd bet money that it's the heater valve. Mine did the same thing, hot air from the passenger side and cool air on the driver's side. I replaced the valve (kind of a bugger, but a DIY job if you're handy) and I get Arctic air out of both sides now. The valve was ~$150 shipped from www.teamfordlv.com and the whole job took me about 5 hours. If I have to do it again, it would be closer to the two hours book time the dealer gets. That includrd bleeding the cooling system and sending my son off for nea coolant.

Same happened to my 2000, the dealer said the director (?) was getting stuck, $750 to fix. I found that by keeping the A/C on recirculate and 60 degrees all the time, it always blows cold...I regulate the amount of airflow with the fan button. Beats spending $750, works fine.

Hello,its seems after reading many issues on the ac air conditioner on the LS, people seem to avoid the answers or suggestions. Maybe if I put it in more detail someone will catch the drift and find a problem to this ongoing problem.My 2000 LS which by the way is a joy to ride :shades: is a 3.9L V8.The ac blows hot air with the setting at maxium cooling. Now I have the dual control temp. I have searched up and down for the low side valve and is still MIA thinking it could be low on R-134a (freon). Now after reading endless forums I heard it may be an electrical problem. The compressor does no sound when turning on the ac. Has anyone had this type of problem and have you solved it already?I thank you in advance. :sick:

If it's low on refrigerant the compressor won't turn on - there's a low pressure safety switch for that. If it is low on refrigerant you need to check for leaks and that requires shop tools - not a DIY thing. You don't want to just refill it with R-134a because it will just leak out again. Just take it to a mechanic and have it checked.

If you want to check your charge to confirm that you have no refrigerant or whatever, the low side port is under the car, attached to the bottom of the compressor. I don't recall if the cap was right there when you looked up or if something had to be removed, it's been 3-4 years since I checked mine. If you have no charge in there, you probably will need to have the system evaluated to see where the leak is. If it is slowly leaking to the point of staying charged for a couple of years, then you should be able to top it off. If you hear the fan start to turn really fast while recharging it, you may be overcharged, and will need to have some refrigerant removed in an environmentally-friendly manner.

:confuse: :confuse: The Pass side A/C goes HOT and the drivers increases a little. Noticed the same with defroster in winter. Dealer can't find since they let car sit until tech can get to it and by then it reset itself. Have noticed that if recirc in on doesn't happen as often. I will try lowering temp from 65 to 60 as someone suggested. but otherwise any ideas??Tom..

lincoln LS 2000 low side port is under the car attached to the compressor. the compressor is on the drivers side front, behind the tire. the quickest way to find it to look behind the tire you will see a black rubber flap that is 3x6 inches. feel or look behind the flap(flashlight is very helpful,day or night) until you see the blue or black cap. The best way to find it is to remove the front driver side tire and get a small stool or cinderblock to sit on, your back and arms will thank you later. you will see the black rubber flap, lift or push it aside and the low side port will be right in front of you. Please be sure to check the pressure with an ac gauge before adding any freon.
